Essex, and State of New Jersey, have invented certain new and useful Improve ments in Processes of Maku'ig an Antlfrlction-Roll, fully described and re iresented in the following specification and the accompanying drawings, forming a part of the [same The object. of this invention is to furnish an improved construction for such antv ver. the making of; rolls byfiwinding .lo'ng strips into rolls ofindefinite length to be afterward cut into .the desired sect ions,'as

the winding of such long strips involves the use of a long machine, 'which unavoidably occupies very considerable space in a factory.

. The present invention'involves the use of rticular charcess ofmaking the same into a hollow, {or use in roller-bearings. The \l-shaped blank in the present invention has two sloping parallel 86 side-arms with straight edges upon their inner and outer sides, and the ends of such arms having tipsof chisel-shape and the outer sides of the arms parallel with one another, so that when the blankis wound into cylindrical form the coils-slope in opposite directions from the'middle portion of the coil and-the chisel-shaped ends form fiat ends upon the finished roll, as they lie upon the straight edges of the arms.

The invention also furnishes means of making rolls with coils exceptionally thick in proportion to their diameter, and which could not therefore-be wound directly upon a mandrel, which is effected by first making a roll with coils of the desired thickness and larger .than the desired diameter, with broad open inter-spams between the coils, and then 7 reducing the diameter of such roll by swaging or analogous means which reduces its. diameter,-'and at the same time stretches the friction rolls as are formed from a V-shaped diameter.

I coils and brings them into contact with one another. The fiat ends desired'upon thecnd of the roll could not be secured in such a mode of manufacture exceptthe arms of the blank were pointed, asshown herein.

A bearing with the rolls operath ely ar-' ranged is shown in thedra'wing with the coils inclined in diverse directions to distribute lubricant, but the rolls may be used i in any other kind of bearing to which they are applicable.

The method 'of winding the blank into rolls is shown in diagrammatic formv herein. The invention will be understood by ref erence to the annexed drawing, in which-' Figure 1 is a longitudinal/section where,

Figs. 1 and 2 show a cylindrical casing A with a shaft ll therein and having friction.- rolls (1' fitted between the shaft and casing. The rolls are shown provided with the usual cage l and the casing with beads E to keep the set of rolls therein. Such construction is only illustrative of one use of the rolls, which rolls'may be used in any form of roller or thrust-bearing to which they are adapted.

()ne of the finished rolls is shown in-l!ig. 6 having coils sloping in opposite dircctionsfrom the middle to opposite ends of the roll, such coils being formed from the paralleledged z1i'n1sb, I',(iftlie V-shapcd blank shown in Fig. 4. Such blank has a point or tongue 0 at one end and a notch (l at the junction where the arms a re united, and the arms also terminate in chiselshaped ends a, the outer edges of which are parallel so as to form flat ends upon the finished roll.

In winding the blanks into coils, the points of the arms are shown in Fig. 3 bent into correspondence with the curvature of the intended coils, and such bent ends are when wmnnlintna rull ivt' the intended lif cnllars are set at afixeil .ilistanee apzrrtnpun the mandrel, which is equal to the length of the intended roll and the \t'ltltlrufthe l lan l these collars sec e to "wind the blanks int The-angle of'thearms inj the blank :himn m Fig. l is n-upnrtinni-il tnith .pitehu'hieh' the arnw assun'le \vhen 'hent int the mils require-(l fur the intelnletl rull, and-the nuti-h (l is at.
